A double pawl latch having a ratchet (14), a primary pawl (34) interacting with the ratchet (14), a secondary pawl (44) interacting with the primary pawl, and a pawl lever (54) interacting with the secondary pawl. The ratchet (14) has a single notch (26) which interacts with the primary pawl (34) to keep the ratchet (14) in a full striker capture position. In the event the primary pawl (34) is unintentionally released, the pawl lever (54) includes a backup pawl (64) that interacts with the ratchet single notch (26), keeping the ratchet (14) in an intermediate striker retaining position where the latch is still closed. The pawl lever (54) initiates the opening of the latch by withdrawing the backup pawl (64) from the path (26′) of the ratchet (14) and by actuating the secondary pawl (44). Momentum from the seal force thereafter drives the primary and secondary pawls open, but in the event the momentum is insufficient the pawl lever (54) can sequentially also open the main pawl (34) after actuating the secondary pawl (44).
